I would appreciate an option to send 1 click unsubscribe links for all users and keep the other options on the page as is.

Listmonk already has this. Go to Settings -> Privacy, and toggle the "Include List-Unsubscribe header" option.

Hi @Justinomics
Thanks for your reply; I have checked to see that function is indeed enabled.
I see the List-Unsubscribe headers in my emails:

Only thing is the URL it gives me, when I visit that it still presents me with a screen to click again before being unsubscribed. Hereby not following the 1-click unsubscribe?

Thanks for your help so far!

Listmonk might also need to support mailto unsubscribe to get rich unsubscribe features in clients

It's valid per the requirements from what I read. I would be worried about false unsubscribes resulting from converting the current method to an actual 1-click method: #1078 (comment)

Visiting is a GET request. The endpoint accepts a POST request as per the spec, which clients like GMail post to, enabling one-click unsubscribe.

It seems like this is broken, or at least not properly configured by default (even when the option is toggled).

I'm using listmonk v4.1 and the emails sent by the campaign do not include the List-Unsubscribe header at all, and I have tried both with and without the option being toggled.

Any help would be greatly appreciated.

@alt-romes if the toggle is enabled, then listmonk definitely includes the header. What SMTP server are you using? It may be possible that the SMTP server is stripping it?
